@JohnKeates, btw, do you experience the same behavior?

Well, no. I did see the same thing happening with other apps that were written in C# and packaged for Mac later on, but that was mostly with older apps. Most of the time when the app opens many versions of itself it's crashing or programmed the wrong way.
